Mobile Device Access Indicators for Network Congestion Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication networks face congestion due to periodic data packet communications from machine-type applications, which can lead to inefficient data transmission and network overload.
Innovation Solution
A mobile communications device dynamically sets and modifies access indicators for traffic types, such as low priority and MTC (Machine-Type Communications) indicators, to manage bearer configurations and control network traffic, allowing for flexible handling of data packets based on their type and priority.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If periodic data packet communications are implemented from machine-type applications, then data transmission functionality is improved, but network congestion occurs
Solution Approach 1:
The invention segments network traffic into different priority levels by introducing priority indicators in bearer establishment requests. Machine-type communication data packets are marked with appropriate priority levels, allowing the network to differentiate and handle them separately from high-priority human communications, thus preventing congestion while maintaining transmission functionality.
Solution Approach 2:
The invention applies local quality by assigning different priority treatments to different types of data traffic within the same network. Specifically, MTC data packets receive differentiated handling based on priority indicators, allowing critical MTC communications to be treated differently from non-critical periodic transmissions, thereby managing congestion locally at the traffic handling level.
2Ease of operation
If access indicators are dynamically set per application and traffic type, then network traffic control is improved, but device complexity increases
Solution Approach 1:
The invention makes the bearer establishment mechanism universal by extending it to handle multiple traffic types and priority levels through a single standardized priority indicator field. This multi-functional approach allows the same bearer setup procedure to accommodate voice, data, and MTC traffic with different priorities without requiring separate complex mechanisms for each traffic type.
Solution Approach 2:
The invention simplifies device complexity by changing only the parameter values (priority indicators) in existing bearer establishment messages rather than modifying the fundamental message structure or protocol. The mobile device simply sets different priority indicator values based on traffic type, allowing dynamic traffic control through parameter adjustment rather than structural complexity.

AI summary
A mobile communications device is arranged to communicate data to and/or from a mobile communications network, the mobile communications device being arranged in operation to communicate an indication of a relative type of data packets for communication via a communications bearer for supporting a communications session of the mobile communications device, the indication of the type of the data packets being used to configure the communications bearer, and to communicate the data packets via the communications bearer to one or more of the infrastructure equipment via one or more of the base stations in accordance with the indication of the type of the data packets, the communication of the data packets via the communications bearer being controlled by the mobile communications network in accordance with the type of data packets being communicated via the communications bearer. By providing an indication of the relative type of the data packets, such as an indication that the data packets are of low priority or are generated or being received by a machine type communication application, the mobile communications network can control the communication of the data packets from the communications bearer differently to data packets communicated via other communications bearer having a higher priority. In one example the mobile communications network buffers data packets from a low priority and/or machine type communication application but not data packets of a higher priority, when the mobile communications network is experiencing congestion.
